    Abstract: A gate driver and a display device including the same, are discussed. The gate driver includes a plurality of stages which are dependently connected to each other. Each of the plurality of pixels includes an output unit which outputs a gate voltage by a voltage of an RQ node, a voltage of a PQ node, and a voltage of a QB node, a first controller which controls the RQ node, a second controller which controls the PQ node, and a third controller which controls the QB node. The gate voltage is configured by a first clock signal having a first phase and a second clock signal having a first phase which is different from the first phase of the first clock signal.
